  2. Brown adipose tissue - Wikipedia

    en.wikipedia.org/wiki/Brown_adipose_tissue

    In addition to heat produced by shivering muscle, brown adipose tissue produces heat by non-shivering thermogenesis. The therapeutic targeting of brown fat for the treatment of human obesity is an active research field. [10] [11]

  3. Thermogenesis - Wikipedia

    en.wikipedia.org/wiki/Thermogenesis

    Thermogenesis is the process of heat production in organisms.It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily (Sauromatum venosum), and the giant water lilies of the genus Victoria.

  4. Thermogenin - Wikipedia

    en.wikipedia.org/wiki/Thermogenin

    The UCP1, or thermogenin, gene likely arose in an ancestor of modern vertebrates, but did not initially allow for our vertebrate ancestor to use non-shivering thermogenesis for warmth. It wasn't until heat generation was adaptively selected for in placental mammal descendants of this common ancestor that UCP1 evolved its current function in ...

  5. Shivering - Wikipedia

    en.wikipedia.org/wiki/Shivering

    Newborn babies, infants, and young children experience a greater (net) heat loss than adults because of greater surface-area-to-volume ratio. As they cannot shiver to maintain body heat, [ citation needed ] they rely on non-shivering thermogenesis .

  6. Fever - Wikipedia

    en.wikipedia.org/wiki/Fever

    In infants, the autonomic nervous system may also activate brown adipose tissue to produce heat (non-shivering thermogenesis). [ 87 ] Increased heart rate and vasoconstriction contribute to increased blood pressure in fever.

    Chills and shivering can be a first sign of hypothermia, Dr. Biernbaum says. You also might feel confused, drowsy, exhausted, or have slurred speech. You also don’t need to be in extremely cold ...

  8. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    Additionally, almost all eutherian mammals (with the only known exception being swine) have brown adipose tissue whose mitochondria are capable of non-shivering thermogenesis. [8] This process involves the direct dissipation of the mitochondrial gradient as heat via an uncoupling protein , thereby "uncoupling" the gradient from its usual ...

  9. Cold and heat adaptations in humans - Wikipedia

    The second is non-shivering, which occurs in brown adipose tissue. [19] Population studies have shown that the San tribe of Southern Africa and the Sandawe of Eastern Africa have reduced shivering thermogenesis in the cold, and poor cold-induced vasodilation in fingers and toes compared to that of Caucasians.
